B) small-signal
C) npn
D) pnp

Question

Quizplus · Accepted Answer

When the electronics equipment has a negative power supply, PNP transistors are typically used. This is because a PNP transistor has a base that is more negative than the emitter, which is ideal for operation with a negative power supply. NPN transistors, on the other hand, have a base that is more positive than the emitter and therefore would not be suitable for use with a negative power supply. Field effect and small-signal transistors are not directly related to the type of power supply used.
